BACKGROUND

1. Field of Invention

The present invention relates generally to compositions comprising 1-chloro-3,3,3-trifluoropropene. More specifically, the present invention provides azeotrope-like compositions comprising 1-chloro-3,3,3-trifluoropropene and uses thereof.

2. Description of Related Art

Fluorocarbon based fluids, including chlorofluorocarbons (“CFCs”) or hydrochlorofluorocarbons (“HCFCs”), have properties that are desirable in industrial refrigerants, blowing agents, heat transfer media, solvents, gaseous dielectrics, and other applications. For these applications, the use of single component fluids or azeotrope-like mixtures, i.e., those which do not substantially fractionate on boiling and evaporation, are particularly desirable.

Unfortunately, suspected environmental problems, such as global warming and ozone depletion, have been attributed to the use of some of these fluids, thereby limiting their contemporary use. Hydrofluoroolefins (“HFOs”) have been proposed as possible replacements for such CFCs, HCFCs, and HFCs. However, the identification of new, environmentally-safe, non-fractionating mixtures comprising HFOs are complicated due to the fact that azeotrope formation is not readily predictable. Therefore, industry is continually seeking new HFO-based mixtures that are acceptable and environmentally safer substitutes for CFCs, HCFCs, and HFCs. This invention satisfies these needs among others.

SUMMARY OF INVENTION

Applicants have discovered that azeotrope-like compositions are formed upon mixing 1-chloro-3,3,3-trifluoropropene (“HFO-1233zd”) with a second component selected from the group consisting of a C₁-C₃ alcohol, a C₅-C₆ hydrocarbon, cyclopentene, a halogenated hydrocarbon selected from 1-chloropropane, 2-chloropropane, and 1,1,1,3,3-pentafluorobutane, water and optionally nitromethane. Preferred azeotrope-like mixtures of the invention exhibit characteristics which make them particularly desirable for number of applications, including as refrigerants, as blowing agents in the manufacture of insulating foams, and as solvents in a number of cleaning and other applications, including in aerosols and other sprayable compositions. In particular, applicants have recognized that these compositions tend to exhibit relatively low global warming potentials (“GWPs”), preferably less than about 1000, more preferably less than about 500, and even more preferably less than about 150.

DESCRIPTION OF PREFERRED EMBODIMENTS

According to certain embodiments, the present invention provides azeotrope-like compositions comprising, and preferably consisting essentially of, HFO-1233zd and a C₁-C₃ alcohol, a C₅-C₆ hydrocarbon, cyclopentene, a halogenated hydrocarbon selected from 1-chloropropane, 2-chloropropane, and 1,1,1,3,3-pentafluorobutane, nitromethane, or water. Thus, the present invention overcomes the aforementioned shortcomings by providing azeotrope-like compositions that are, in preferred embodiments, substantially free of CFCs, HCFCs, and HFCs and have very low global warming potentials have low ozone depletion potential, and which exhibit relatively constant boiling point characteristics.

As used herein, the term “azeotrope-like” relates to compositions that are strictly azeotropic or that generally behave like azeotropic mixtures. An azeotropic mixture is a system of two or more components in which the liquid composition and vapor composition are equal at the stated pressure and temperature. In practice, this means that the components of an azeotropic mixture are constant-boiling or essentially constant-boiling and generally cannot be thermodynamically separated during a phase change. The vapor composition formed by boiling or evaporation of an azeotropic mixture is identical, or substantially identical, to the original liquid composition. Thus, the concentration of components in the liquid and vapor phases of azeotrope-like compositions change only minimally, if at all, as the composition boils or otherwise evaporates. In contrast, boiling or evaporating non-azeotropic mixtures changes the component concentrations in the liquid phase to a significant degree.

As used herein, the term “consisting essentially of”, with respect to the components of an azeotrope-like composition, means the composition contains the indicated components in an azeotrope-like ratio, and may contain additional components provided that the additional components do not form new azeotrope-like systems. For example, azeotrope-like mixtures consisting essentially of two compounds are those that form binary azeotropes, which optionally may include one or more additional components, provided that the additional components do not render the mixture non-azeotropic and do not form an azeotrope with either or both of the compounds.

The term “effective amounts” as used herein refers to the amount of each component which, upon combination with the other component, results in the formation of an azeotrope-like composition of the present invention.

Unless otherwise specified, the term HFO-1233zd means the cis-isomer, the trans-isomer, or some mixture thereof.

As used herein, the term cis-HFO-1233zd with respect to a component of an azeotrope-like mixture, means the amount cis-HFO-1233zd relative to all isomers of HFO-1233zd in azeotrope-like compositions is at least about 95%, more preferably at least about 98%, even more preferably at least about 99%, even more preferably at least about 99.9%. In certain preferred embodiments, the cis-HFO-1233zd component in azeotrope-like compositions of the present invention is essentially pure cis-HFO-1233zd.

As used herein, the term trans-HFO-1233zd with respect to a component of an azeotrope-like mixture, means the amount trans-HFO-1233zd relative to all isomers of HFO-1233zd in azeotrope-like compositions is at least about 95%, more preferably at least about 98%, even more preferably at least about 99%, even more preferably at least about 99.9%. In certain preferred embodiments, the trans-HFO-1233zd component in azeotrope-like compositions of the present invention is essentially pure trans-HFO-1233zd.

As used herein, the term “ambient pressure” with respect to boiling point data means the atmospheric pressure surrounding the relevant medium. In general, ambient pressure is 14.7 psia, but could vary +/−0.5 psi.

The azeotrope-like compositions of the present invention can be produced by combining effective amounts of HFO-1233zd with one or more other components, preferably in fluid form. Any of a wide variety of methods known in the art for combining two or more components to form a composition can be adapted for use in the present methods. For example, HFO-1233zd and methanol can be mixed, blended, or otherwise combined by hand and/or by machine, as part of a batch or continuous reaction and/or process, or via combinations of two or more such steps. In light of the disclosure herein, those of skill in the art will be readily able to prepare azeotrope-like compositions according to the present invention without undue experimentation.

Fluoropropenes, such as CF₃CCl═CH₂, can be produced by known methods such as catalytic vapor phase fluorination of various saturated and unsaturated halogen-containing C3 compounds, including the method described in U.S. Pat. Nos. 2,889,379; 4,798,818 and 4,465,786, each of which is incorporated herein by reference.

EP 974,571, also incorporated herein by reference, discloses the preparation of 1,1,1,3-chlorotrifluoropropene by contacting 1,1,1,3,3-pentafluoropropane (HFC-245fa) in the vapor phase with a chromium based catalyst at elevated temperature, or in the liquid phase with an alcoholic solution of KOH, NaOH, Ca(OH)2 or Mg(OH)2. The end product is approximately 90% by weight of the trans isomer and 10% by weight cis. Preferably, the cis isomers are substantially separated from the trans forms so that the resultant preferred form of 1-chloro-3,3,3-trifluoropropene is more enriched in the cis isomer. Because the cis isomer has a boiling point of about 40° C. in contrast with the trans isomer boiling point of about 20° C., the two can easily be separated by any number of distillation methods known in the art. However, a preferred method is batch distillation. According to this method, a mixture of cis and trans 1-chloro-3,3,3-trifluoropropene is charged to the reboiler. The trans isomer is removed in the overhead leaving the cis isomer in the reboiler. The distillation can also be run in a continuous distillation where the trans isomer is removed in the overhead and the cis isomer is removed in the bottom. This distillation process can yield about 99.9+% pure trans-1-chloro-3,3,3-trifluoropropene and 99.9+% cis-1-chloro-3,3,3-trifluoropropene.

In a preferred embodiments, the azeotrope-like composition comprises effective amounts of HFO-1233zd and a C₁-C₃ alcohol. Preferably, the C₁-C₃ alcohol is selected from the group consisting of methanol, ethanol, and isopropanol. In certain preferred embodiments, the HFO-1233zd is trans-HFO-1233zd.

Preferably, these optional additives do not affect the basic azeotrope-like characteristic of the composition.

Blowing Agents:

In another embodiment of the invention, provided are blowing agents comprising at least one azeotrope-like mixture described herein. Polymer foams are generally of two general classes: thermoplastic foams and thermoset foams.

Thermoplastic foams are produced generally via any method known in the art, including those described in Throne, Thermoplastic Foams, 1996, Sherwood Publishers, Hinkley, Ohio, or Klempner and Sendijarevic, Polymeric Foams and Foam Technology, 2^(nd) Edition 2004, Hander Gardner Publications. Inc, Cincinnati, Ohio. For example, extruded thermoplastic foams can be prepared by an extrusion process whereby a solution of blowing agent in molten polymer, formed in an extruder under pressure, is forced through an orifice onto a moving belt at ambient temperature or pressure or optionally at reduced pressure to aid in foam expansion. The blowing agent vaporizes and causes the polymer to expand. The polymer simultaneously expands and cools under conditions that give it enough strength to maintain dimensional stability at the time corresponding to maximum expansion. Polymers used for the production of extruded thermoplastic foams include, but are not limited to, polystyrene, polyethylene (HDPE, LDPE, and LLDPE), polypropylene, polyethylene terephthalate, ethylene vinyl acetate, and mixtures thereof. A number of additives are optionally added to the molten polymer solution to optimize foam processing and properties including, but not limited to, nucleating agents (e.g., talc), flame retardants, colorants, processing aids (e.g., waxes), cross linking agents, permeability modifiers, and the like. Additional processing steps such as irradiation to increase cross linking, lamination of a surface film to improve foam skin quality, trimming and planning to achieve foam dimension requirements, and other processes may also be included in the manufacturing process.

In general, the blowing agent may include the azeotrope-like compositions of the present invention in widely ranging amounts. It is generally preferred, however, that the blowing agents comprise at least about 15% by weight of the blowing agent. In certain preferred embodiments, the blowing agent comprises at least about 50% by weight of the present compositions, and in certain embodiments the blowing agent consists essentially of the present azeotrope-like composition. In certain preferred embodiments, the blowing agent includes, in addition to the present azeotrope-like mixtures, one or more co-blowing agents, fillers, vapor pressure modifiers, flame suppressants, stabilizers, and like adjuvants.

In certain preferred embodiments, the blowing agent is characterized as a physical (i.e., volatile) blowing agent comprising the azeotrope-like mixture of the present invention. In general, the amount of blowing agent present in the blended mixture is dictated by the desired foam densities of the final foams products and by the pressure and solubility limits of the process. For example, the proportions of blowing agent in parts by weight can fall within the range of about 1 to about 45 parts, more preferably from about 4 to about 30 parts, of blowing agent per 100 parts by weight of polymer. The blowing agent may comprise additional components mixed with the azeotrope-like composition, including chlorofluorocarbons such as trichlorofluoromethane (CFC-11), dichlorodifluoromethane (CFC-12), hydrochlorofluorocarbons such as 1,1-dichloro-1-fluoroethane (HCFC-141b), 1-chloro-1,1-difluoroethane (HCFC-142b), chlorodifluoromethane (HCFC-22), hydrofluorocarbons such as 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1-difluoroethane (HFC-152a), 1,1,1,3,3-pentafluoropropane (HFC-245fa), and 1,1,1,3,3-pentafluorobutane (HFC-365mfc), hydrocarbons such as propane, butane, isobutane, cyclopentane, carbon dioxide, chlorinated hydrocarbons alcohols, ethers, ketones and mixtures thereof.

In certain embodiments, the blowing agent is characterized as a chemical blowing agent. Chemical blowing agents are materials that, when exposed to temperature and pressure conditions in the extruder, decompose to liberate a gas, generally carbon dioxide, carbon monoxide, nitrogen, hydrogen, ammonia, nitrous oxide, of mixtures thereof. The amount of chemical blowing agent present is dependent on the desired final foam density. The proportions in parts by weight of the total chemical blowing agent blend can fall within the range of from less than 1 to about 15 parts, preferably from about 1 to about 10 parts, of blowing agent per 100 parts by weight of polymer.

In certain preferred embodiments, dispersing agents, cell stabilizers, surfactants and other additives may also be incorporated into the blowing agent compositions of the present invention. Surfactants are optional, but preferably are added to serve as cell stabilizers. Some representative materials are sold under the names of DC-193, B-8404, and L-5340 which are, generally, polysiloxane polyoxyalkylene block co-polymers such as those disclosed in U.S. Pat. Nos. 2,834,748, 2,917,480, and 2,846,458, each of which are incorporated herein by reference. Other optional additives for the blowing agent mixture include flame retardants or suppressants such as tri(2-chloroethyl)phosphate, tri(2-chloropropyl)phosphate, tri(2,3-dibromopropyl)-phosphate, tri(1,3-dichloropropyl) phosphate, diammonium phosphate, various halogenated aromatic compounds, antimony oxide, aluminum trihydrate, polyvinyl chloride, and the like. With respect to thermoset foams, in general any thermoset polymer can be used, including but not limited to polyurethane, polyisocyanurate, phenolic, epoxy, and combinations thereof. In general these foams are produced by bringing together chemically reactive components in the presence of one or more blowing agents, including the azeotrope-like composition of this invention and optionally other additives, including but not limited to cell stabilizers, solubility enhancers, catalysts, flame retardants, auxiliary blowing agents, inert fillers, dyes, and the like. With respect to the preparation of polyurethane or polyisocyanurate foams using the azeotrope like compositions described in the invention, any of the methods well known in the art can be employed, see Saunders and Frisch, Volumes I and II Polyurethanes Chemistry and Technology (1962) John Wiley and Sons, New York, N.Y. In general, polyurethane or polyisocyanurate foams are prepared by combining an isocyanate, a polyol or mixture of polyols, a blowing agent or mixture of blowing agents, and other materials such as catalysts, surfactants, and optionally, flame retardants, colorants, or other additives.

It is convenient in many applications to provide the components for polyurethane or polyisocyanurate foams in preblended formulations. Most typically, the foam formulation is preblended into two components. The isocyanate and optionally certain surfactants and blowing agents comprise the first component, commonly referred to as the “A” component. The polyol or polyol mixture, surfactant, catalysts, blowing agents, flame retardant, and other isocyanate reactive components comprise the second component, commonly referred to as the “B” component. Accordingly, polyurethane or polyisocyanurate foams are readily prepared by bringing together the A and B side components either by hand mix for small preparations and, preferably, machine mix techniques to form blocks, slabs, laminates, pour-in-place panels and other items, spray applied foams, froths, and the like. Optionally, other ingredients such as fire retardants, colorants, auxiliary blowing agents, water, and even other polyols can be added as a third stream to the mix head or reaction site. Most conveniently, however, they are all incorporated into one B Component as described above.

Any organic polyisocyanate can be employed in polyurethane or polyisocyanurate foam synthesis inclusive of aliphatic and aromatic polyisocyanates. Preferred as a class are the aromatic polyisocyanates. Typical aliphatic polyisocyanates are alkylene diisocyanates such as tri, tetra, and hexamethylene diisocyanate, isophorene diisocyanate, 4,4′-methylenebis(cyclohexyl isocyanate), and the like; typical aromatic polyisocyanates include m-, and p-phenylene diisocyanate, polymethylene polyphenyl isocyanate, 2,4- and 2,6-toluenediisocyanate, dianisidine diisocyanate, bitoylene isocyanate, naphthylene 1,4-diisocyanate, bis(4-isocyanatophenyl)methene, bis(2-methyl-4-isocyanatophenyl)methane, and the like.

Preferred polyisocyanates are the polymethylene polyphenyl isocyanates, particularly the mixtures containing from about 30 to about 85 percent by weight of methylenebis(phenyl isocyanate) with the remainder of the mixture comprising the polymethylene polyphenyl polyisocyanates of functionality higher than 2.

Typical polyols used in the manufacture of polyurethane foams include, but are not limited to, aromatic amino-based polyether polyols such as those based on mixtures of 2,4- and 2,6-toluenediamine condensed with ethylene oxide and/or propylene oxide. These polyols find utility in pour-in-place molded foams. Another example is aromatic alkylamino-based polyether polyols such as those based on ethoxylated and/or propoxylated aminoethylated nonylphenol derivatives. These polyols generally find utility in spray applied polyurethane foams. Another example is sucrose-based polyols such as those based on sucrose derivatives and/or mixtures of sucrose and glycerine derivatives condensed with ethylene oxide and/or propylene oxide.

Examples of polyols used in polyurethane modified polyisocyanurate foams include, but are not limited to, aromatic polyester polyols such as those based on complex mixtures of phthalate-type or terephthalate-type esters formed from polyols such as ethylene glycol, diethylene glycol, or propylene glycol. These polyols are used in rigid laminated boardstock, can be blended with other types of polyols such as sucrose based polyols, and used in other polyurethane foam applications such as described above.

Catalysts used in the manufacture of polyurethane foams are typically tertiary amines including, but not limited to, N-alkylmorpholines, N-alkylalkanolamines, N,N-dialkylcyclohexylamines, and alkylamines where the alkyl groups are methyl, ethyl, propyl, butyl, and the like and isomeric forms thereof; and hetrocyclic amines. Typical, but not limiting examples are triethylenediamine, tetramethylethylenediamine, bis(2-dimethylaminoethyl)ether, triethylamine, tripropylamine, tributylamine, triamylamine, pyridine, quinoline, dimethylpiperazine, piperazine, N,N-dimethylcyclohexylamine, N-ethylmorpholine, 2-methylpiperazine, N,N-dimethylethanolamine, tetramethylpropanediamine, methyltriethylenediamine, and the like, and mixtures thereof.

Optionally, non-amine polyurethane catalysts are used. Typical of such catalysts are organometallic compounds of bismuth, lead, tin, titanium, antimony, uranium, cadmium, cobalt, thorium, aluminum, mercury, zinc, nickel, cerium, molybdenum, vanadium, copper, manganese, zirconium, and the like. Included as illustrative are bismuth nitrate, lead 2-ethylhexoate, lead benzoate, ferric chloride, antimony trichloride and antimony glycolate. A preferred organo-tin class includes the stannous salts of carboxylic acids such as stannous octoate, stannous 2-ethylhexoate, stannous laurate, and the like, as well as dialkyl tin salts of carboxylic acids such as dibutyl tin diacetate, dibutyl tin dilaurate, dioctyl tin diacetate, and the like.

In the preparation of polyisocyanurate foams, trimerization catalysts are used for the purpose of converting the blends in conjunction with excess A component to polyisocyanurate-polyurethane foams. The trimerization catalysts employed can be any catalyst known to one skilled in the art, including, but not limited to, glycine salts and tertiary amine trimerization catalysts and alkali metal carboxylic acid salts and mixtures of the various types of catalysts. Preferred species within the classes are potassium acetate, potassium octoate, and N-(2-hydroxy-5-nonylphenol)methyl-N-methylglycinate.

Dispersing agents, cell stabilizers, and surfactants can be incorporated into the present blends. Surfactants, which are, generally, polysiloxane polyoxyalkylene block co-polymers, such as those disclosed in U.S. Pat. Nos. 2,834,748, 2,917,480, and 2,846,458, which are incorporated herein by reference.

Other optional additives for the blends can include flame retardants such as tris(2-chloroethyl)phosphate, tris(2-chloropropyl)phosphate, tris(2,3-dibromopropyl)phosphate, tris(1,3-dichloropropyl)phosphate, diammonium phosphate, various halogenated aromatic compounds, antimony oxide, aluminum trihydrate, polyvinyl chloride, and the like. Other optional ingredients can include from 0 to about 3 percent water, which chemically reacts with the isocyanate to produce carbon dioxide. This carbon dioxide acts as an auxiliary blowing agent.

Also included in the mixture are blowing agents or blowing agent blends as disclosed in this invention. Generally speaking, the amount of blowing agent present in the blended mixture is dictated by the desired foam densities of the final polyurethane or polyisocyanurate foams product. The proportions in parts by weight of the total blowing agent blend can fall within the range of from 1 to about 45 parts of blowing agent per 100 parts of polyol, preferably from about 4 to about 30 parts.

The polyurethane foams produced can vary in density from about 0.5 pound per cubic foot to about 40 pounds per cubic foot, preferably from about 1.0 to 20.0 pounds per cubic foot, and most preferably from about 1.5 to 6.0 pounds per cubic foot. The density obtained is a function of how much of the blowing agent or blowing agent mixture disclosed in this invention is present in the A and/or B components, or alternatively added at the time the foam is prepared.

Foams and Foamable Compositions:

Certain embodiments of the present invention involve a foam comprising a polyurethane-, polyisocyanurate-, or phenolic-based cell wall and a cell gas disposed within at least a portion of the cells, wherein the cell gas comprises the azeotrope-like mixture described herein. In certain embodiments, the foams are extruded thermoplastic foams. Preferred foams have a density ranging from about 0.5 pounds per cubic foot to about 60 pounds per cubic foot, preferably from about 1.0 to 20.0 pounds per cubic foot, and most preferably from about 1.5 to 6.0 pounds per cubic foot. The foam density is a function of how much of the blowing agent or blowing agent mixture (i.e., the azeotrope-like mixture and any auxiliary blowing agent, such as carbon dioxide, chemical blowing agent or other co-blowing agent) is present in the molten polymer. These foams are generally rigid but can be made in various grades of softness to suit the end use requirements. The foams can have a closed cell structure, an open cell structure or a mixture of open and closed cells, with closed cell structures being preferred. These foams are used in a variety of well known applications, including but not limited to thermal insulation, flotation, packaging, void filling, crafts and decorative, and shock absorption.

In other embodiments, the invention provides foamable compositions. The foamable compositions of the present invention generally include one or more components capable of forming foam, such as polyurethane, polyisocyanurate, and phenolic-based compositions, and a blowing agent comprising at least one azeotrope-like mixture described herein. In certain embodiments, the foamable composition comprises thermoplastic materials, particularly thermoplastic polymers and/or resins. Examples of thermoplastic foam components include polyolefins, such as polystyrene (PS), polyethylene (PE), polypropylene (PP) and polyethyleneterepthalate (PET), and foams formed therefrom, preferably low-density foams. In certain embodiments, the thermoplastic foamable composition is an extrudable composition.

In certain embodiments, provided is a method for producing such foams. It will be appreciated by those skilled in the art, especially in view of the disclosure contained herein, that the order and manner in which the blowing agent is formed and/or added to the foamable composition does not generally affect the operability of the present invention. For example, in the case of extrudable foams, it is possible to mix in advance the various components of the blowing agent. In certain embodiments, the components of the foamable composition are not mixed in advance of introduction to the extrusion equipment or are not added to the same location in the extrusion equipment. Thus, in certain embodiments it may be desired to introduce one or more components of the blowing agent at first location in the extruder, which is upstream of the place of addition of one or more other components of the blowing agent, with the expectation that the components will come together in the extruder and/or operate more effectively in this manner. In certain other embodiments, two or more components of the blowing agent are combined in advance and introduced together into the foamable composition, either directly or as part of premix which is then further added to other parts of the foamable composition.

In a preferred embodiment, the azeotrope-like compositions of this invention may be used as solvents in sprayable compositions, either alone or in combination with other known propellants. The solvent composition comprises, more preferably consists essentially of, and, even more preferably, consists of the azeotrope-like compositions of the invention. In certain embodiments, the sprayable composition is an aerosol.

In certain preferred embodiments, provided is a sprayable composition comprising a solvent as described above, an active ingredient, and optionally, other components such as inert ingredients, solvents, and the like.

Suitable active materials to be sprayed include, without limitation, cosmetic materials such as deodorants, perfumes, hair sprays, cleaning solvents, lubricants, insecticides as well as medicinal materials, such as anti-asthma medications. The term medicinal materials is used herein in its broadest sense to include any and all materials which are, or at least are believe to be, effective in connection with therapeutic, diagnostic, pain relief, and similar treatments, and as such would include for example drugs and biologically active substances.

Solvents and Cleaning Compositions:

In another embodiment of the invention, the azeotrope-like compositions described herein can be used as a solvent in cleaning various soils such as mineral oil, rosin based fluxes, silicon oils, lubricants, etc., from various substrates by wiping, vapor degreasing, or other means. In certain preferred embodiments, the cleaning composition is an aerosol.

EXAMPLES

The invention is further illustrated in the following example which is intended to be illustrative, but not limiting in any manner. For the relevant examples, an ebulliometer of the general type described by Swietolslowski in his book “Ebulliometric Measurements” (Reinhold, 1945) was used.

Example 1

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which was further equipped with a Quartz Thermometer or a thermistor was used. About 10 cc of trans-HFO-1233zd was charged to the ebulliometer and then methanol was added in small, measured increments. Temperature depression was observed when methanol was added, indicating a binary minimum boiling azeotrope had been formed. From greater than 0 to about 51 weight percent methanol, the boiling point of the composition changes less than about 1.3° C. The boiling points of the binary mixtures shown in Table 1 changed by less than about 0.02° C. Thus the compositions exhibited azeotrope and/or azeotrope-like properties over these ranges. To conform result two such ebulliometers were set up side by side of which one contained pure solvent and the other one was set up with trans-HFO-1233zd and 2^(nd) component was added as mentioned before. The difference of temperatures in the two was also measured.

Example 2

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which was further equipped with a Quartz Thermometer or a thermistor was used. About 35 g trans-HFO-1233zd is charged to the ebulliometer and then n-pentane was added in small, measured increments. Temperature depression was observed when n-pentane was added to trans-HFO-1233zd, indicating a binary minimum boiling azeotrope had been formed. From greater than 0 to about 30 weight percent n-pentane, the boiling point of the composition changes less than about 0.8° C. The boiling points of the binary mixtures shown in Table 2 changed by less than about 0.02° C. Thus the compositions exhibited azeotrope and/or azeotrope-like properties over these ranges.

Example 3

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which was further equipped with a Quartz Thermometer or a thermistor was used. About 17 g trans-HFO-1233zd is charged to the ebulliometer and then isopentane was added in small, measured increments. Temperature depression was observed when isopentane was added to trans-HFO-1233zd, indicating a binary minimum boiling azeotrope had been formed. From greater than about 0 to about 30 weight percent isopentane, the boiling point of the composition changed by about 0.8° C. or less. The boiling points of the binary mixtures shown in Table 3 changed by less than about 0.2° C. Thus the compositions exhibited azeotrope and/or azeotrope-like properties over these ranges.

Example 4

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which was further equipped with a Quartz Thermometer or a thermistor was used. About 17 g neopentane is charged to the ebulliometer and then trans-HFO-1233zd was added in small, measured increments. Temperature depression was observed when trans-HFO-1233zd was added to neopentane indicating a binary minimum boiling azeotrope had been formed. As shown in Table 4, compositions comprising from about 19 to about 49 weight percent trans-HFO-1233zd had a change in boiling point of 0.1° C. or less. Thus the compositions exhibited azeotrope and/or azeotrope-like properties over at least this range.

Example 5

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which was further equipped with a Quartz Thermometer or a thermistor was used. About 18 g trans-HFO-1233 is charged to the ebulliometer and then trans-1,2-DCE was added in small, measured increments. Temperature depression was observed when trans-1,2-DCE was added to trans-HFO-1233, indicating a binary minimum boiling azeotrope was formed. From greater than about 0.01 to about 53 weight percent trans-1,2-DCE, the boiling point of the composition changed by about 0.7° C. or less. The boiling points of the binary mixtures shown in Table 4 changed by less than about 0.3° C. Thus the compositions exhibited azeotrope and/or azeotrope-like properties over these ranges.

Example 26

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which is further equipped with a Quartz Thermometer is used. An amount of cis-HFO-1233zd is charged to the ebulliometer and then nitromethane is added in small, measured increments. Temperature depression is observed when nitromethane is added to cis-HFO-1233, indicating a binary minimum boiling azeotrope is formed. The compositions exhibit azeotrope and/or azeotrope-like properties over a range of about 95 to 99.9 weight percent cis-1233zd and about 0.1 to about 5 weight percent nitromethane. More pronounced azeotrope and/or azeotrope-like properties occur over a range of about 97 to 99.9 weight percent cis-1233zd and about 0.1 to about 3 weight percent nitromethane; and even more pronounced over a range of about 99 to 99.9 weight percent cis-1233zd and about 0.1 to about 1 weight percent nitromethane.

Example 27

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which is further equipped with a Quartz Thermometer is used. An amount of cis-HFO-1233zd is charged to the ebulliometer and then n-pentane is added in small, measured increments. Temperature depression is observed when n-pentane is added to cis-HFO-1233, indicating a binary minimum boiling azeotrope is formed. The compositions exhibit azeotrope and/or azeotrope-like properties over a range of about 20 to 99.5 weight percent cis-1233zd and about 0.5 to about 80 weight percent n-pentane. More pronounced azeotrope and/or azeotrope-like properties occur over a range of about 50 to 99.5 weight percent cis-1233zd and about 0.5 to about 50 weight percent n-pentane; and even more pronounced over a range of about 60 to 99.5 weight percent cis-1233zd and about 0.5 to about 40 weight percent n-pentane.

Example 28

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which is further equipped with a Quartz Thermometer is used. An amount of cis-HFO-1233zd is charged to the ebulliometer and then neopentane is added in small, measured increments. Temperature depression is observed when neopentane is added to cis-HFO-1233, indicating a binary minimum boiling azeotrope is formed. The compositions exhibit azeotrope and/or azeotrope-like properties over a range of about 5 to 50 weight percent cis-1233zd and about 50 to about 95 weight percent neopentane. More pronounced azeotrope and/or azeotrope-like properties occur over a range of about 20 to 45 weight percent cis-1233zd and about 55 to about 80 weight percent neopentane; and even more pronounced over a range of about 30 to 40 weight percent cis-1233zd and about 60 to about 70 weight percent neopentane.

Example 29

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which is further equipped with a Quartz Thermometer is used. An amount of cis-HFO-1233zd is charged to the ebulliometer and then n-hexane is added in small, measured increments. Temperature depression is observed when n-hexane is added to cis-HFO-1233, indicating a binary minimum boiling azeotrope is formed. The compositions exhibit azeotrope and/or azeotrope-like properties over a range of about 80 to 99.5 weight percent cis-1233zd and about 0.5 to about 20 weight percent n-hexane. More pronounced azeotrope and/or azeotrope-like properties occur over a range of about 90 to 99.5 weight percent cis-1233zd and about 0.5 to about 10 weight percent n-hexane; and even more pronounced over a range of about 95 to 99.5 weight percent cis-1233zd and about 0.5 to about 5 weight percent n-hexane.

Example 30

An ebulliometer consisting of vacuum jacketed tube with a condenser on top which is further equipped with a Quartz Thermometer is used. An amount of cis-HFO-1233zd is charged to the ebulliometer and then isohexane is added in small, measured increments. Temperature depression is observed when isohexane is added to cis-HFO-1233, indicating a binary minimum boiling azeotrope is formed. The compositions exhibit azeotrope and/or azeotrope-like properties over a range of about 70 to 99.5 weight percent cis-1233zd and about 0.5 to about 30 weight percent isohexane. More pronounced azeotrope and/or azeotrope-like properties occur over a range of about 85 to 99.5 weight percent cis-1233zd and about 0.5 to about 15 weight percent isohexane; and even more pronounced over a range of about 93 to 99.5 weight percent cis-1233zd and about 0.5 to about 7 weight percent isohexane.

Example 31

An azeotrope-like mixture containing 98% by weight trans-HFO-1233zd with about 2% by weight methanol is loaded into an aerosol can. An aerosol valve is crimped into place and HFC-134a is added through the valve to achieve a pressure in the can of about 20 PSIG. The mixture is then sprayed onto surface demonstrating that the azeotropic mixture is useful as an aerosol.

Examples 32-57

The steps of Example 31 are generally repeated for Examples 32-57, except that the azeotrope-like mixture identified in the Table below is used instead of trans-HFO-1233zd and methanol.
